Allium spurium G.Don, Mem. Wern. Nat. Hist. Soc. vi. 59 (1827) Fig. 1K-O

Allium dauricum N.Friesen, Fl. Sibir. (Arac.-Orchidac.) 58 (1987). Type: Russia. Transbaicalia Orientalis, pagum Kyra, in valle fuvii Bukukum, in prato substepposo, 31 Aug. 1964, G.Peschkova & L.Ovczinnicova s.n. (Holotype: LE!; Isotypes: NSK).

Type.

Russia (Siberia, location in doubt). Type specimen not designated (protologue).

Notes.

Allium spurium is occasionally confused with A. spirale because of its more or less similar growth habit, but the most distinctive characters include narrower leaf blades and scapes and smaller floral parts (Table 3 ; Fig. 1L-N ). This species is newly recorded for South Korea, and the new vernacular name ‘Gak-si-du-me-bu-chu’ is given. Besides, Cheongnyangsan of South Korea is the disjunct southernmost limit for geographical distribution of A. spurium (Fig. 5 ).
